Can I paint them red with cheap gloss, and put spinning wheel embelishers on too..........nice

Hmmm. This thread is starting to sound like the April Fools "Can I convert my rear brakes to drums to stop the brake dust" thread. Also the "painted disks" thread I remember seeing too.

My feeling is that if a mod gives performance benefits, is affordable or offers considerable cosmetic benefit then However, I agree with Walkie. Big rear disks would look silly, and as there is negligible performance increase then no thanks.

And £400

Depends what you want to do with the car.

I looked at 308mm rears with AP 4 pots (to go with the planned 332mm fronts and AP 6 pots).

As for use standard calliper so no benefits - bolleaux! Pure and simple, sorry.

I'd like to follow you about in it an annoy you at every opportunity.

A bit like you do with me.

Try post 78 in "what do you hate about other road users"

That should get you going. In fact you might even close the thread.......

Hmm - let's not go there

I would have thought bigger discs, even with the same calipers/pads, would improve fading as the heat gets dispersed over a greater surface area.

Not argueing that the rest (calipers/pads) wouldnt have a bigger impact, but still

Bigger brakes make the car stop faster. If you did manage to fit bigger ones at the rear, I'm sure it wouldnt look silly. More proportioned if nothing else, esp if you have massive fronts and tiny, tiny rears

Bigger disc's with the standard caliper are going to stop you faster than smaller disc's with the same caliper. It's all down to simple physics. Saying that why spend alot of money on somethnig like rear disc's when they only take a small proportion of the brake force anyway

That's it - little benefit for pretty high cost. I suppose it will improve fading a little if you can actually manage to get the rears to fade.

I'll reply to your points in the other thread in a mo but, as to my question as to what you wish to do with your car, it is a serious question. As you seem to be incapable of working it out, I'll give you some options below as to possible uses and whether it is worth doing:

1) Are you just using it for normal road driving? Nope not worth the money doing an upgrade
2) Do you drive fast on normal roads, by fast I mean averaging over 60 on A and B roads? I'd check whether the uprated fronts give you want you want and how you feel the balance of the car is.
3) Do you use the car on track? Are you fairly "agressive" when on track? If the answer to the first is yes and the second is no, just uprate the rear pads - Greenstuff or Pagid Blues (if available) would be OK. If the answer to both is yes, do the upgrade, especially if you do lots of track stuff.

Correct

Not so Glass'opper, don't they have brake force distribution? If so if the fronts are being used hard, won't it transfer some braking force to the raers, possibly causing them to work harder than they are capable of? Just curious and on this I'm prepared to be corrected.

Option 2. (for legal reasons, I must point out that I don't go over the speed limit) Thanks for the advice. I'll give it a try when the front ones are on, and see what I think.

Cheers

Re the EBD, my citroen xsara had that, and it was quite amazing, I've not felt it's presence in the vrs yet, obviously not trying hard enough....

You shouldn't feel it really.

I noticed it with uprating all my brakes and playing with the bias and the abs kick in point - felt like the car was being sucked into the tarmac

Cheers for that, although I would find it very difficult to know if the rears had faded I think. Half the time, even under tremendously hard braking on B roads, they don't feel as though they are doing a great deal. Upgrading them seems like too big a job, and far too expensive for what little might be acheived, so thanks for all of your advice guys.........Conclusion...I'll leave it for now, and if the bigger front ones don't make me happy, then perhaps I need a different car.

I can't really do that though. Mainly because I don't know how to, and the car is only 2 months old. I don't really want to be meddling with things I don't know enough about.

I'm used to other cars where you can feel the rears biting hard, such as the xsara, bx 16 valve (long time ago) and even my pug estate. Must just be a french thing. These brakes were great before I had the remap, but now on familiar roads, i'm carrying a hell of alot more speed and therefore need to be able to slow the car alot faster. Like you said, I will be in a better position to make my mind up when the new fronts are on. I can always put fast road discs and pads in instead of oem octy/audi tt that will be on it initially.
